Vaccine manufacturers step up production to prevent infections

As influenza viruses spread, vaccine makers in China are speeding up efforts to guarantee supply, in order to safeguard citizens during the ongoing flu outbreak.

The country reported 420 influenza outbreaks from Nov 27 to Dec 3, a more than 4,100 percent surge from last year during the same period, said the Chinese National Influenza Center.

To tackle the outbreaks, citizens have been advised to get vaccinated and take protective measures to prevent infections. To combat likely cross infections, several vaccine companies have also launched polyvalent vaccines.
